A multifunctional insulating barrier structure for power batteries

Abstract

The invention discloses a multifunctional insulating barrier structure for power batteries. Each insulating grid body (1) is installed between two batteries (2) distributed in a power supply system, and each side limit The inner surface of the bar (3) is connected with the insulating grille body (1), and a wiring harness limiting groove (4) is provided on the top of each side limiting bar (3), and a wiring harness limiting groove (4) is provided on each side limiting bar (3). ) is provided with feet (5), on the surface of the insulating grid (1) there are a number of grid bars vertically distributed, between the grid bars are arranged as heat dissipation air ducts (7), one of the grid bars The grid bar is grid bar I (6), and the remaining grid bars are grid bar II (8). The top and bottom of grid bar I (6) are respectively equipped with a temperature probe limit device and a lower limit block (9). The top and the bottom of grid bar II (8) are upper limit block (10) and lower limit block (9) respectively.

Description

technical field [0001] The invention relates to a multifunctional insulating barrier structure for a power battery. Background technique [0002] At present, because the power supply system is mainly used in pure electric or hybrid city buses or buses, and the working environment is relatively harsh, the safety requirements for battery packs are very high. The heat of the power battery cannot be taken away quickly during use, which will cause heat to accumulate in the battery box, and the temperature will gradually rise, resulting in battery failure or even the risk of fire and explosion. Therefore, it is necessary to ensure the ventilation and heat dissipation of the battery, and to accurately detect each The temperature of a temperature control point. The power supply system will fall off due to vibration, sharp turns and other conditions in harsh working conditions, which will affect the safety of the power supply system. Therefore, it must be ensured that the power batt...

Problems solved by technology

The heat of the power battery cannot be taken away quickly during use, which will cause heat to accumulate in the battery box, and the temperature will gradually rise, resulting in battery failure or even the risk of fire and explosion. Therefore, it is necessary to ensure the ventilation and heat dissipation of the battery, and to accurately detect each The temperature of a temperature control point

The power supply system will cause the battery to fall off due to vibration, sharp turns, etc. in harsh working conditions, which will affect the safety of the power supply system. Therefore, it must be ensured that the power battery will not move during use.
